How to assign and retrieve values from JTextField in java swing

[Rao's]

Hi friends recently I was creating one desktop based application using Swing Technology. So the condition is that whenever my Frame opens the Textfield must have some of the predefine values and also the user can enter the required values into that fields and when click on the submit button, the programs retrieve the values from TextFields and display that in message box. So if you guys have any of the information or any of the suggestion or code for this type of Program then please does the reply.

According to my information this is easy to assign as well as to retrieve the values from JTextfield in Swing based java programming. So for that you can make use of the predefine method of JTextfield Class.
The two useful method getText(); and setText(); can be used for getting and setting the values from the Textfield

So with the help of this two inbuilt method this is possible to assign as well as retrieve the data to/from JTextfield

According to my information you just try this code may this will help you out.

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class Abc extends JFrame implements ActionListener
{
JButton btn1;
JTextField txt1,txt2;
Abc()
{
setSize(500,500);
setDefaultCloseOperation(3);
setVisible(true);
setTitle(“Text Field Demo”);
btn1= new JButton(“Submit”);
txt1=new JTextField(10);
txt2= new JTextField(10);
//Assigning values to both the TextField
txt1.setText(“Enter the Name Here”);
txt2.setText(“Enter your Age here”);
setLayout(new FlowLayout());
//Adding component to the main Frame
add(txt1);
add(txt2);
btn1.addActionListener(this);
add(btn1);

}
public void actionPerformed(ActionEvent ae)
{
String s1, s2;
//Retrieving textField Values
s1= txt1.getText();
s2=txt2.getText();
//Displaying values in Message box
JOptionPane.showMessageDialog(null,”Your name is ”+ s1+ “/n and your Age is”+s2);
}
public static void main(String str[])
{
Abc a= new Abc();
}
}

In order to retrive values from JTextField use getText() method; and in order to assign value to JTextField make use of setText() method.
